While the invention mayxoe embodied in Various' forms, I' prefer the' forni .illustrated by Figs. 1 to 5,-this 'being Well adapted for placket fasteners of substantially the size shown byFig. l5.' l `The basefl has acentral opening and fforms'an' inexpansible frame, surrounding y. the opening. The Wall of said" opening,

forms v'an internal shoulder '14 which is inexpansible and 'constitutes the preferred 75 embodiment'of the' above-mentioned inter- -nal engaging means. The base forms the marginal portion of. an originally lat'blank, the central portion of which. is olset from the bese and forms a hollow boss. The'v 8.0- 'continuity'of the said boss is interrupted by 4slots 16 extending across thewall and across lthe headjportion' of the boss, the Wall beingjthus subdividedintoa plurality of resilient flanges 17 integral with the' base. The outer edgev of eachilange is provided 'with an eilitern'aly shoulder 18, the series';of shoulders 1.8 constituting the preferred em- .bodifment ofthe'above-me'n'tioned external engaging,` means. Said 'externalfshoulders 90 .which are yieldingly' 'supported by the danges"17 are adapted to snapv into engagelmentv'vith th'ej continuous nyielding internal shoulder 14, .when the two 'members are assembledv or` nested,` alsfshown by'Fig. 2, `the members beingV thus interengag'ed with.. su'iiiien't` tenacityv or .all practicalfpurposes. 4'Tlijebase portions: ofthe interengaged menl.bers are spaced from eachother, that -the Vmembers .may be. readily* separated' by" n'- sertin'g a finger Snail between'fthembase 'por-1 Ytionsp The spacing "of the'base portions prevents either -base portion from"`o`hafng stitlws-ielgselwithL the' @ther bese. Pcf-F bers may-also .be 'separated 1.05 by.. t seed. @mma-0r. both-10H11@ carryingpartsE 2O -sfecured to 'the members. shown-rby Fi 2,4on`e' of said" carrying partsfgbear .on, t o, embossed side-of one' apn the opposite side of' l110 'other member. The internal' shoulder-Muis preferably circular and the-external shoulders V18 are preferably segments ofa circle, While .the margin, of the base 13 is prefer turning.

-A I l I head portion of the boss 1s converted by th'e ably re'ctamgular.- This form' of )the Ibase margin is preferred,'because it enables the base' to be confined with its orifices 13?- in predetermined positions .with referencepto theneedle lof a sewing machine employed to'sew-the member to-a carrying part,' the machine being. provided with suitab1e.po, sitioning'means engaging oppositejed'ges of the base and Vpreventing the member z from The'y segmental. tongues: into which the slots .16, prevent undesirable flexibility of the flanges' 17,' 'and assistin/'maintaining a suioientlyfirm engagement between) the externalf'shoulders 18 and 'thel internal shoulhe base having" margin I formed ,Lto

the above-described embodiment of the invention the outer shoulders.- 8 5 constitute "Units or sections of an, expan ble annular Sis shoulder, the inner annular shoulder v14. beinginexpansible. It is essential-that one f said annular shoulders be resilient or'.

capable Qfbeing contracted 'and of expanding .aftercontractiom and that 'the other shoulder be inexpansible 'or -rigid 4and 'adapted to casefcontraction ofthe-resilient shoulder duringthe operation of *connectingv the member 'and to 'llmitthe expansion of operatively'connected.. vInthe Imodification shown by Figs.

The base is rovided with disconnected slots 20, .exten ing from its margin through' the innershoulder, here 'l designated by 14a, 'the 'inner'ends of said Slots'being in the annular' Wall' of the boss.'
